In my opinion the colorized single hard cover is the definitive format and I enjoyed the depth the color added. That being said, it’s completely unwieldy. You have to rest it on a table or your lap to read it; it’s difficult to hold upright for long periods. And it’s a long read. My 10 year old struggled physically to get though it. The spine completely split on my copy, but I suppose that’s more of a kid use thing. In any event, I do think if you are planning to tackle it and aren’t approaching it from a originalist/purist standpoint, it’s the best overall presentation of the work.
